A security system having two-way communication with a central monitoring station. The security system is equipped with a computerized control and communications unit. The control and communications unit is connected to a position determination device and to a calling unit. The control and communications unit is also connected to several intrusion detection devices. Upon direction of the control and communications unit, for example, in response to the detection of a violation of an intrusion detection device, the calling unit establishes a communications link with the central monitoring station and communicates thereto the status and location of the vehicle in which the security system is located. The control and communication device is operable to receive commands from a handset electrically connected thereto. The central monitoring station, by communicating with the control and communications unit, is operable to control functional units of the vehicle. The central monitoring station includes a display on which maps showing the location of vehicles in communication with the monitoring station and information about such vehicles. An operator at the monitoring station may direct equipment in the monitoring station to initiate calls to law enforcement organizations and emergency response vehicles. Other systems and methods are disclosed.

Programmable vehicle monitoring and security system having multiple access verification devices

An apparatus for monitoring operation a vehicle apparatus includes sensors for sensing G-forces on the vehicle and for generating output signals proportional to a forward G-force, a reverse G-force, a left direction G-force, and a right direction G-force on the vehicle. The apparatus permits an authorized user to set a selected maximum G-force limit for each direction. The apparatus stores G-force output signals generated by the sensors which are higher than the maximum selected limit for each direction. An oven heats each sensor to a substantially constant predetermined temperature, thereby improving the accuracy of the output signals from the sensor upon fluctuation of an ambient temperature adjacent the apparatus. The apparatus detects when the apparatus has been disconnected from a power supply to alert an owner of the vehicle that the vehicle may have been driven without the monitoring apparatus in operation.

A security system (10) suitable for use in monitoring property at an outdoor site that includes a portable housing (12) that supports a motion detector (14) for sensing motion within a detection zone. The security system further includes an ultrasonic transducer (74) and several alarm generators capable of repelling a human intruder, including a high intensity illumination source (18), high decibel siren (82), strobe light (19), and a speaker (78) for transmitting a prerecorded message. When an intrusion is initially detected by the motion detector, the ultrasonic transducer is activated to emit an ultrasonic signal that is irritating to nonhuman animals, thus clearing the detection zone of nonhuman intruders. If after sounding of the ultrasonic transducer motion is still detected, one or more of the alarms is activated. Additionally, an automatic telephone dialer (86) may be included in the system and activated by the system as another type of alarm, in response to detected intrusion. The system is integrated within the portable housing and is resistant to false alarms, making it suitable for use in monitoring property stored at an outside site. A method for utilizing the security system to protect property is also disclosed.

Portable security system for outdoor sites

A remote watch (FIG. 7 ) design for a car security system, comprising of a display screen and base 706 with keypad 704 . A user of the remote watch will not only be able to keep track of the time but also will be able to arm/lock, disarm/unlock and remotely start their vehicle by pushing specific buttons on the watch. It is common for people to lose or misplace their keys along with the keyless remote that is attached to the keys. Since the watch is placed on the users wrist, the user never has to worry about damage due to dropping it on a hard surface, in liquids (ex. water), or even losing their keyless remote as you would by having a keyless remote attached to keys or a key chain. If the user ever loses their keys, the remote watch will now allow the user to still have access to their vehicle without their keys, thus giving the user the freedom to store an extra set of keys in their vehicle in case they lose the original ones.

An anti-theft device and method includes a motion sensor for detecting motion and generating signals. The present invention also includes an anti-tamper mechanism for sounding an alarm when the apparatus is tampered with. The motion sensor and anti-tamper sensor are coupled to a computer which is in stand-by mode most of the time to conserve energy. When signals are sent to the computer, its software interprets the signals and generates an alarm when the computer determines that at least one of a plurality of predetermined motion values are met. The predetermined motion values include frequency of motion, duration of motion and intensity of motion. The alarm is sounded in increments of varying duration according to the interpretation of the signals by the software, thus providing warning signals and full alarms.

Programmable microprocessor based motion-sensitive alarm

A user-programmable sensor system for generating an alarm signal upon detection of an alarm event is disclosed. The system is particularly suited for use in vehicle security systems. The system employs a three axes accelerometer as a shock/motion detector, and the transducer outputs are summed and the composite signal filtered to provide several channels, each covering a specific frequency or frequency band. The outputs of the channels are digitized and processed by a microprocessor. An event is characterized by seveal signal parameters with an alarm event triggered by the simultaneous occurrence of several predetermined conditions, and not just one condition. The limit values for the signal parameters which are required to qualify a shock/motion event as an alarm event may be readily programmed by the user at any time or place. The system further includes a glass breakage transducer and analyzes higher frequency components of the transducer signal to sense a glass breakage event when predetermined signal parameters are exceeded and when energy from the shock detector correlates with the glass breakage signal. The correlation with several parameters substantially reduces false alarm signals resulting from ambient high frequency noises, such as caused by passing siren-sounding vehicles or low-flying jets or helicopters.
